Hy Prime is a water based primer, specifically formulated for internal timber floors. It is fully compatible with Hy Traffic and Hydrothane floor finishes. Hy Prime penetrates and fills open grain timber providing an even appearance and foundation for subsequent coatings of waterborne timber seal.
Hy Prime should only be applied to new or freshly sanded timber. This product is designed to minimize the problem of edge bonding which occurs when climatic conditions cause floorboards to shrink naturally.
